I've been working primarily in Go for the past five years, including some extremely complex projects, and I have never once wished I had dependency injection. It has been wonderful. I have used dependency injection - previously I worked on a C# project for years, and that used DI - but I adore Go's simplicity and I never want to use anything else (except for JS for UI, via Electron or Wails for desktop).
Do you write unit tests with objects mocked via interfaces? Or polymorphism via interfaces? Those are the main reasons to use DI.
I guess I have to start calling function invocation with generic parameters, fancy names (like "dependency injection" ^^)
Relevant:
I also prefer the simpler explanation.
